CASE STUDY
BAILOUT IMPLANTATION OF A NEW SINGLE-BRANCHED STENT GRAFT FOR THE AORTIC ARCH
(A) Computed tomography angiogram shows aortic arch pseudoaneurysm at the level of the distal anastomosis.
(B) Three-dimensional reconstruction shows compression on the pulmonary artery

(B) Three-dimensional reconstruction shows complete aortic arch exclusion and side branch in innominate artery
PATIENT INFORMATION
74-year-old male, COPD, previous MI, right nephrectomy (Ca), Diabetes Mellitus, Dyslipidemia, Button Bentall + Hemi Arch for Acute Type A Dissection
REASON TO TREAT
Pseudoaneurysm of the left posterolateral side of the ascending aorta at the level of the distal anastomosis illustrating significant increase and compression of the pulmonary artery (Fig. 1). Due to risk of fistulization into the pulmonary artery, the patient was scheduled for urgent pseudoaneurysm exclusion with NEXUS™.
DEBRANCHING
A right common carotid artery, left common carotid artery, left subclavian artery bypass was surgically performed and six days later, to allow complete recovery from the bypass surgery, the endovascular procedure was carried out.
NEXUS IMPLANTATION
NEXUS™ was successfully deployed during an uneventful procedure with an optimal outcome lasting 150 minutes with 42 minutes of fluoroscopy.
PROCEDURAL OUTCOME
Due to an uneventful and minimally invasive procedure, the patient was able to be discharged 7 days post op. Six month follow up CT angiogram (Fig 2) shows stable position of NEXUS™ and total exclusion of the anastomotic pseudoaneurysm.
PHYSICIAN'S PUBLISHED COMMENTS
Cibin et al1 stated “Owing to their ready availability, singlebranch off-the-shelf aortic arch endovascular prostheses are a valid option in case of urgent and emergent cases.”
“A combined operation, bypass, and endovascular procedure at the same time, although technically feasible, would be long and with less neurologic control than a staged approach.”
